Answer:

She must score 90 points

Step-by-step explanation:

Find the average of the first 2 tests

76 + 80 = 156

Divide the sum of the first 2 tests by how many tests there were

156 ÷ 2 = 78

Multiply 82 by 3

82 x 3 = 246

Subtract 156 from 246

246 - 156 = 90

Add all the numbers together to get the average

90 + 80 + 76 = 246

246 ÷ 3 = 82

Hope this helps!
